既然pyobjc能夠使用cocoa提供的這麼多庫函式，那對我們有沒有一些實際的作用呢？聯想到在自動化測試中，appscript有些操作目前還是無法實現的，例如：

無法實現點選螢幕任意座標（appscript中未找到類似的api）

無法雙擊某個控制元件（通過appscript兩次呼叫控制元件的click方法是不生效的）

無法實現控制元件上右鍵……

現在，這些appscript無法完成的操作，通過pyobjc又找到了另一條實現的途徑，我們可以藉助pyobjc，來構造並觸發我們需要的滑鼠事件，cocoa的 CoreGraphics庫中就包含了構造所有滑鼠事件的方法，在蘋果開發者網站上了解了這些函式的使用方式後，實現一個fakemouse，能否完成的操作有：點選螢幕任意座標、在任意座標雙擊、在任意座標滑鼠右鍵、移動滑鼠至某個座標、滑鼠拖拽等。具體實現程式碼如下：
